FAQs about IEQc3.2 :

Do non-regularly occupied areas such as bathrooms and corridors have to be flushed-out?

For LEED NC addition projects, do existing non-renovated areas need to be flushed-out or tested?

For IAQ testing, how many sample points are necessary in non-mechanically ventilated spaces?

Can testing be done over various days?

I'm confused about the 11/1/2011 LEED addendum that removed the "1/25,000 SF or each contiguous area whichever is larger" language from the credit requirement. How do we determine the number of sampling locations for testing?

Is it possible for the flush-out start date to vary by ventilation zone?

Should a parking garage be included in a flush-out, if it is in a basement and not fully open to the outdoors?

Do the outdoor air minimum quantities have to be met for each individual space, or for the building square footage as a whole?

flush-out documentation

Do we have to document flush-out somehow for the credit compliance? Is any report or declaration needed?

Not exactly. Currently the LEED form does not require that you upload any data for "proof" that your ran the units for the required amount of time and that you maintained the 60/60 requirement. However, the reviewer may question how you "could" prove it if you didn't install temporary temperature and humidity sensors or already have permanent sensors. I recommend you describe your method to measure the OSA quantities and maintain 60/60 in the narrative to avoid questioning.
